実験手順

To a warm solution of 4-[[(dimethylamino)methylene]amino]-3-pyridinol (3.0 g) in dry tetrahydrofuran (60 mL) was added phenyl isocyanate (2.05 mL). The reaction mixture was stirred at room temperature for 1.5 hours and filtered. The solid was washed with dry diethyl ether, air dried, and dried under high vacuum and refluxing ethanol for 4 hours to yield 4.19 g of solid, m.p. 151 ° C.
